Strong Suction Cups
Color: Silver
I didn't realize that this caddy came with the option to use suction cups or adhesive hooks. I opted for the suction cups and was pleasantly surprised at their strength. I loaded the caddy up with a couple of sponges, fingernail brush, and a dishwashing brush (filled with liquid soap) and have had no problems with the caddy remaining strongly secured. It's a great little organizer and looks really nice.

GREAT Suction!! Looks fantastic!
Color: Silver, Color: Silver
I wanted to find a sponge holder with great suction for our ceramic sink. This is the REAL DEAL! I saw one or two complaints on the reviews below but obviously they are doing something wrong, because if you just follow the instructions (make sure the sink is clean and dry where you stick it), it works perfectly. I've had it for about 3 weeks now and we use it every single day and it has never slipped even once. The suction cups are big and made of good plastic so they really do the job. It hasn't budged from the spot where I placed it. It's also easy to take the caddy off of the suction cups when you want to clean the sink without moving the suction cups. You can peel them off easily and reposition them but they will not move unless you want them too. It's also the perfect size and looks great. Perfect for holding a stick sponge upright so that the soap doesn't leak out of it.
